In this comprehensive study, there is an innovative plant layout that seamlessly integrates the Allam cycle’s oxy-combustion capabilities with the renewable energy harnessing potential of a concentrated solar power (CSP), all fueled by a supercritical CO2(sCO2) Brayton cycle. This innovative process is based on the burning of natural gas in an oxygen-rich environment, which results in a strong high-pressure stream of CO2. This sCO2 is simultaneously channeled into the CSP system. The sCO2 experiences temperature elevation within the CSP, which is made possible by concentrated solar energy. The initial setup involves two distinct configurations: the first being a semi-closed cycle featuring oxy-combustion of natural gas for energy input, while the second adopts a closed system design with solar thermal energy as the primary energy input source. In the natural gas Allam cycles, components include a combustor, turbine, recuperator, compressors interconnected with an intercooler, a pump, and two coolers. The generation of almost pure CO2, primed and ready for carbon capture, is an essential lead of this revolutionary technique. This dual benefit of electricity generation coupled with carbon capture readiness marks a significant step forward in sustainable power generating. This approach not only shifts the emphasis to increased efficiency, but it also emphasizes the critical need for carbon reduction in today’s ever-changing energy scenario. The shown configuration in the paper is such that it has incorporated a photovoltaic (PV) system to support the plants running needs by giving the electricity produced to the air separation unit and minimize the power consumption done by the whole of the power plant.
